Attribute filled in SWO1 but not in workflow container

['Mark Pyc']

G'day Rob,
 
Word of warning:
I don't really trust the use of the 'global' data of the object to handle
persistence between method calls. Many things can work wonderfully in SWO1
where the transaction ensures that everything remains resident in memory,
but won't work in a live workflow.
 
Even in the case where you have two background methods in a row - forget
that, they can be bundled into a single method.
 
Even if the scenario works in testing of the workflow and the data remains
in memory as desired, in a real situation an error which stops the
workflow between the 'SET' and the use of the attribute will cripple you.
 
As Joc recommends, use a table to store the data. If you don't have a
table, make a new one. If there is no logical key to use, you may need to
use something like WF instance id...??
 
Have fun,
Mark

Hi Rob,
Um...what's your attribute code to read the Logid attribute?
 
Normally attributes are read from the database or calculated.
So you would normally have your method update the appropriate table.
Otherwise the data won't be persistent.
 
You could try using an object-private-
intermediate field to hold the data and see if that works in your given
scenario.
Should be ok if the object doesn't get refreshed or re-instanced in the
meantime.
 
However it would be safer to save the data somewhere.
 
Jocelyn

It still doesn't work in the workflow...
The method is now:
 
begin_method set_logid changing container.
 
DATA:
      lognumber LIKE balhdr-lognumber,
      logid LIKE balhdr-lognumber.
swc_get_element container 'LogNumber' lognumber.
logid = lognumber.
swc_set_element container 'LogID' logid.
 
end_method.

Rob,
It sets it back into the object (not workflow) container - from which
object
attributes are returned to the workflow.
Try it.

But that sets the element back into the container, not as an attribute,
does
it??

Maybe the commented out set of the container element?

Hi all.
 
 
 
I created an attribute LOGID and a method SET_LOGID.
 
The attribute is virtual.
 
 
 
The method works fine when I test it in SWO1, the attribute is filled and
it
can be used in a secondary method for the workflow.
 
But when I test it in the workflow, the attribute is NOT filled. Bindings
are right, so what could be the problem??
 
 
 
The method:
 
BEGIN_METHOD SET_LOGID CHANGING CONTAINER.
 
 
 
DATA:
 
      LOGNUMBER LIKE BALHDR-LOGNUMBER.
 
  SWC_GET_ELEMENT CONTAINER 'LogNumber' LOGNUMBER.
 
  OBJECT-LOGID = LOGNUMBER.
 
*  swc_set_element container LOGNUMBER OBJECT-LOGID.
 
 
 
END_METHOD.
 
 
 
Does anybody know??
 
 
 
Regards,
